Mold-Masters designs small heating element
Mold-Masters Ltd. of Georgetown, Ontario, claims it has developed the world's smallest 220-volt heating element for use with its new MIM-Dura line of small hot-runner nozzles.
The company claims its heating elements are 21/2 times more accurate than conventional units. Multiple injection nozzles can be controlled accurately under a single zone, without significant deviation in drop-to-drop power on multicavity systems.

Spectra-Beam shows flaws in film, sheet
Eurotherm Gauging Systems Inc. offers an infrared sensor, the Spectra-Beam HR, that checks film and sheet.
Eurotherm, of Billerica, Mass., was the original developer of a technology called full-spectrum infrared, which uses a beam of infrared light to focus on the web, showing imperfections. The new Spectra-Beam HR improves on that by using a more-focused infrared beam, giving the unit greater profile resolution.
Spectra-Beam HR can work with Eurotherm's existing CIMline controller or the Windows NT-based System 21, which was introduced last year.

Web monitor detects 24 different defects
WebScan 1000, a web monitoring system from Focus Automation Systems Inc., uses special cameras and a choice of light sources to match the material. It can be integrated easily into film production.
The system detects 24 types of defects, including low-contract stains and streaks. The Windows NT-based operating system can store setups for 500 web products.
Focus Automation is based in Waterloo, Ontario.

Micrometer measures extruded pipe, tubing
Beta LaserMike's bench-top Model 283 Laser Micrometer measures extruded products such as tubing and pipe, without making contact with the sample.
A motorized fixture allows the operator to quickly measure the outside diameter and wall thickness of the sample, as it automatically calculates the inside diameter.
The micrometer uses computer graphics and a touch screen with push-buttons for frequently used operations.
The company is based in Dayton, Ohio.

Thickness profiler gauges thin material
The Traversing Thickness Profiler from Systronics Inc. can measure nonconductive material, such as plastic film, to an accuracy of plus or minus 0.0006 inches.
The system makes readings every tenth of an inch while traversing across the web. An operator interface displays, stores and prints thickness data, said the company in Norcross, Ga.

Tradesco introduces 3-level stack mold
A three-level stack mold from Tradesco Mold Ltd. of Rexdale, Ontario, includes a fully balanced hot-runner system that uses Tradesco's Valveless Melt Transfer System.
The technology means that all parts fill evenly, under the same injection pressure and with no increase over two-level stack molds in cycle or clamp-tonnage requirements.
Typical applications include industrial lids, thin-wall containers, medical disposables and housewares.
